This is what I'm driving toward. Since it's a volume dependant problem..I can almost bet its a dual 2 ohm, and the shop wired it to 1 ohm. As far as I know the PDX isn't stable at 1 ohm...?
Wow. Like I said, the downside of having your stuff installed instead of doing it yourself. Stupid things like that. Idiots.they had the wires from the amp on 1 coil //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif . I told him to move the negative to the other coil.
